Took bite out of high strength well that consisted of 5000+ psi concrete, masonry brick and cinderblocks. It wasn't anywhere close to fast but it got the job done well. Water helped speed up the process but it was extremely messy...The free cutting disk works great too.

Price was great, delivery was fast, great product, thank you very much. Drilled 2 - Two and a half inch holes 13" deep thru poured solid concrete wall. Took about 2 hours. Im very pleased

The bit worked great and was a terrific price. It went through brick and concrete block as described, with several breaks to cool off my hand drill that I used for the project. I would definitely recommend this product for its performance and very competitive price. Be sure to wear a good mask to prevent silicates from getting into your lungs and ear protection. It will be loud! When receiving the bit, I was concerned that the diamonds supposedly on the cutter portion of the bit were absent from view, but it really did the job with very little wear upon the tool.
